Good start. The music is probably the most redeeming part of the game. The animation and pixel art is okay, buy the puzzles/map layout is too big for the puzzles that you're putting in the game. If your looking for some advice to improve the game, try and make the music change parts of the environment, or start using levers, pressure plates or some other mechanics into the game.
Decent game.

fun visual style... looking forward to seeing this progress more... though I'm not sure if there are any other controls aside from using the arrow keys... but the visuals do have me on the hook :3
